Anti-fog surgical mask with a middle vapor barrier

ABSTRACT

A surgical mask having a surgical body for covering the nose and mouth of a wearer, and a surgical mask include a surgical mask body, a middle vapor barrier, and middle tie(s) or ear loop(s). The vapor barrier is positioned between a mouth and a nose of a wearer&#39;s face to inhibit vapor, e.g., the moisture in exhale.

BACKGROUND 1. Technical Field

The present invention pertains in general to surgical mask and, more particularly pertains to a surgical mask which reduce or eliminate fogging that may occur on eye wear or an eye-shield worn by a user of the surgical mask.

2. Background of the Invention

The present invention relates to surgical face masks and more particularly to a mask having a vapor barrier for preventing clouding or fogging of optical aids used by a wearer of a surgical mask.

Surgical masks are worn by surgeons and others in operating and the like to substantially prevent contamination or infection from airborne bacteria exhausted from the breath of the wearer. Surgical masks are generally lightweight in construction and contain several features designed for adaption to an individual wearer's features.

The surgical mask is comprised of a rectangular shaped surgical mask body (not shown) of pleated or non-pleated material, an ear loop attached to one side and an ear loop attached to the other side. The ear loops are designed to fit over the ears of the wearer. In this manner, the surgical mask therefore provides some conformation to the face of the wearer to prevent contaminants from entering the environment due to the inhaling and exhaling of the wearer.

One type of mask is illustrated in U.S. Pat. No. 5,699,792 entitled face mask with enhanced facial seal, issued on Dec. 23, 1997 to Barumann et al.

Although a variety of facial shapes to most closely approximate the wearer's features, it is inadequate to prevent the wearer's breath from being vented between the face of the wearer and the surgical mask. Since these masks are not designed to prevent from fogging by mouth breathing, some breath exhausts through the lower portion of the mask into the vicinity of the wearer's eyes. The breath, being warm and moist, holds fluid vapor which readily condenses on cooler objects. Such cooler objects may be present in the airconditioned operating rooms in the form of glass lenses of optical aids used by the surgeons and assistants. Such optical aids include spectacles, surgical loupes and surgical microscopes.

The exhaust of exhaled breath is resisted to some degree by the surgical mask itself, promoting flow of breath under the surgical mask. Because warm air rises, the wearers breath also has a natural tendency to rise under the surgical mask and through the upper surgical mask surface area producing fogging of the optical aids positioned in the vicinity of the wearer's eyes. This obscuration of the wearer's vision is a nuisance at best and a hazard at worst. This shortcoming of the prior art mask often requires the surgeon to pause to clear the lenses of condensation interfering with his or her vision.

The necessity for clear vision during surgical procedures as well as the time expediency element has fostered a need for preventing such fogging.

Referring to FIG. 1, there is illustrated a perspective view of a surgical mask 10 having a surgical mask body 20 and a vapor barrier 30, shown in FIG. 6, disposed on a wearer 100 with glasses 200 according to an aspect of the present invention.

The surgical mask body 20 typically includes a plurality of layers, generally at least three layers (not shown), although some mask bodies may have only one or two layers.

Typically, at least one of the layers includes a thermoplastic material, for example, polypropylene. In some embodiments, the layers include an outer cover web, a filtering material, and a shaping layer. The outermost layer of the surgical mask is typically an outer cover web that is exposed to the exterior atmosphere when the mask is positioned on a wearer's face. If no cover web is present, an outer shell, for example, may be the outermost layer. A soft inner liner or shell may also be included on the surface of the mask body opposite the outermost layer or cover web to provide a smooth, soft surface for contact with the skin. When a wearer inhales, air is drawn from the mask exterior through the various layers into the mask interior. In most surgical mask bodies 20, at least one layer includes a filtering material.

FIG. 2 illustrates a surgical mask according to an aspect of the present invention.

Referring to FIG. 2, a surgical mask 10 may include a surgical mask body 20, a vapor barrier 30, and mask tie 41, 42, 50L, 50R according to an aspect of the present invention.

The two upper sides ties 41, are attached to both upper corner of the surgical mask body 20 at a point 60 and to an opposite corner on the same upper edge thereof to a point 70. Two lower side ties 42 are attached on a diametrically opposite side of the surgical mask body 20 from the two upper ties 41 with one end thereof attached to a point 80 on one corner of the surgical mask body 20 and to a point 90 on the opposite corner thereof. In addition, two left and right middle ties, 50L, 50R, are attached to at points, 51L and 51R, respectively.

The tie(s) allow to extend generally about head of the wearer for securing the surgical mask to the wearer.

Positioning the two left and right middle ties 50L, 50R in this manner results in securing tightly the vapor barrier 30 with the face of wearer when wearing the surgical mask as shown in FIG. 1.

The vapor barrier 30 can be positioned in a middle of the surgical mask body 20 as shown in FIG. 2.

However, it is understood that the position of the vapor barrier 30 may be varied in accordance with the mask types and/or size according to an aspect of the present invention.

A left side ear loop 40L is attached to left upper corner of the surgical mask body 20 at a point 60 and to a left lower corner on the same edge thereof to a point 80. A right-side ear loop 40R is attached on a diametrically opposite side of the surgical mask body 20 from the left side ear loop 40L with one end thereof attached to a point 70 on one corner of the surgical mask body 20 and with the other end thereof attached to a point 90 on the opposite corner. In addition, a left middle loop 50LP is attached at a point 51L and at the point 80 or near the point 80 and a right middle loop 50RP is attached at a point 51R and at the point 90 or near the point 90, respectively.

However, it is not limited thereto.

Referring now back to FIGS. 2-6, there is illustrated a view of the attachment point 60 of the ear loops 41, 40L. The ear loops 41, 40L can be fabricated from a combination of texturized polyester and lycra spandex. The material is formed from 90.33 percent of 78 Denier texturized polyester and 9.67 percent of 40 Denier Lycra spandex. This material is cut into a thin member and, due to the properties of the material, this strip will “roll over”, that is, the edges thereof will curl up. In this manner, an elastically deformable member is formed that has a semicircular cross section to provide some comfort behind the ears of the wearer.

Due to the properties of the ties or ear loops, 41, 50L, 50R, 40L, 40R, 50LP, and 50RP, heat bonding techniques such as radio frequency (RF) heat bonding can be used. Given our invention, persons skilled in the art would realize that the use of a synthetic fabric, such as the lycra spandex/polyester fabric of the invention, allows the use of a high-frequency heat bonding technique to attach the fabric to another synthetic fabric, and further would understand that heat bonding cannot be used with conventional rubber or thread-coated rubber loops because their structural integrity would be destroyed. Further, persons skilled in the art would realize, given our invention, that ear loops made out of a lycra spandex/polyester fabric have more “flecxibility” than conventional rubber or thread-coated rubber ear loops, and as such are much more comfortable to the sensitive skin behind the ear of the wearer.

According to an aspect of the present invention, to attach the ear loops 41, 40L at the point 60, it is necessary to apply suitable amounts of heat and pressure thereto.

The band or bands that are used for the ear loops to support a surgical mask on a wearer's face include a combination of an elastic constituent and a fibrous thermoplastic constituent to provide a band with some elastic characteristics and to allow the strap to be attached to the surgical mask body by the application of heat and pressure.

Generally, the width of a band, for use on filtering face masks, ranges from about 1/16 inch to one inch, typically from about ⅛ to ½ inch. The most common bands for use with filtering face masks range about 3/16 to ¼-inch wide. However, it is not limited thereto. The width of the band can be varied.

The width of the band can be adjusted by using a varying number of threads when braiding the band. For example, six threads will typically provide a wider band than a band that has only four threads of the same size. Both the width and thickness of the band can be adjusted by using different sizes of threads. Threads having a larger diameter or cross-sectional area will generally provide a band thicker and wider than threads having a smaller diameter or cross-sectional area. Similarly, the width and thickness of the band can be adjusted by using varied sizes of fibrous thermoplastic yarns. However, it is not limited thereto.

In one embodiment of the present invention, the band, having the elastic constituent and the thermoplastic constituent, is permanently attached to the surgical mask body by the application of heat and pressure to the point where the band and body adjoin.

The combination of the heat and pressure is generally sufficient to partially or fully melt a portion of the band and/or a portion of the surgical mask body, thereby creating a bond between the tie(s), ear loop(s) or band and the surgical mask body. Depending on the construction of the surgical mask body, the outermost layer may or may not be the portion of the surgical mask body that melts. Rather, in some embodiments, an interior layer of the surgical mask body, for example, the filtering material, may be the layer that melts.

Ear loops, ties, or band may be formed from various types of material. Ear loop(s) and/or tie(s) are preferably formed from thermally bonded polypropylene having a basis weight of 1.5 to 1.65 ounces per square yard. This particular type of material can be ultrasonically welded, stitched or heat and pressure bonded in various patterns to provide a resilient securing means for use in attaching the tie(s) or ear loop(s) to the surgical mask body 20 according to an aspect of the present invention.

Referring back to FIGS. 1-6, a surgical mask 10 may include a surgical mask body 20, and a vapor barrier 30. The vapor barrier 30 is positioned between a mouth and a nose of a wearer face to inhibit vapor, e.g., the moisture in exhaled breath, from passing between the surgical mask 10 and the wearer's face. When the vapor barrier 30 is positioned between the wearer's nose and mouth, as shown in FIG. 1, moisture from exhaled breath is prevented from exiting the surgical mask in a manner that would cause fogging of the wearer's eyewear, e.g., eyeglasses, goggles, and face shields. The vapor barrier 30 can assist in directing the exhaled breath into the layers of the surgical mask, through the layers of the mask body portion, and into the space created at sides of the mask where the mask portion and wearer's face are not in sealing contact with each other.

While aspects of the present have been described in connection with what are presently considered to be practical exemplary embodiments, it will be appreciated by those skilled in the art that various modifications and changes may be made without departing from the scope of the present disclosure.
